From a brief look here it seems you could only benefit from 3D Analayze if you have a video card that doesn't already support transform and lighting. Listing the hardware specifications of your PC could help us answer your question.

This is only useful for very old (older than ~2003) video cards without Hardware Transform and Lighting units. It emulates this functionality to allow software requiring this feature to work on these graphics cards, and in a few cases to allow certain software to run faster.

Yes it does bro i have run many games using this it also speeds up games if they already work for ex nfsmw the first one i didnt have many graphics options before 3danalyze after i used it it cleared so much lag and opened more options like visual treatment etcc
